'To all whom t may con/ecrit.; Be it known that we, IsAAoW. Git is, of New Bedford, in the county of Bristol and ,State of Massachusetts, and. CHARLES W. TQBEY, of Fairhaven, in the county of Bristol and State of Itiassachusetts, have invented A, certain new 'and useful Improvements in Wheels, of which the following is a specification. i

This inveiitionis an improvement in the wheels, and consists in. certain novel constructions ...and combinations of parts as will be hereinafter described and claiinedf 7 AIn the drawing Figure 1 is a side view of a portion of4 a wheeleinbodying my invention. F ig. 2 is a cross-section on about the line 2 2 of Fig. 1. Fig. 3 is across-section on about the line '3`3 of Fig. 1;- Fig. 4 is a section on about the line 4- -4 of Fig. 2. Fig. 5 is a plan view of one of the grooved` supporting plates. Figs. (l to l2, inclusive, show ditl'ei'ent cross-sectional forms of the rings constituting the siipportii'ig tire. Fig. 13 is a detail view showing the connection between the inner ends of the opposite studs, and Fig. l-t illustrates in side view one of the grooved supporting plates:

.lu carrying out our invention we einplov'` an elastic tire A which may beef solid-rub' ben-and is provided alon'g its opposite sides with ciiciiinfcreiitial grooves- A receiving the reinforcin ciinil'erence with a series of cavities l which und thc circumference il receive devices presently described. The reinforcing rings l are rods or stout wires inl the form of rings and to tli'cse reinforcingr rings are connected at intervals stints l) arranged opposite tli'e ingw ihriiugh the outer portions ol. the tire A into the cavities (l and having atI their inner ends, within said cavitics,hool\'s l) wliichaieconnected, within the cavities (l, by -linlts (P, as liest shown in Figs.

For supporting the elastic tire we. employ Y a siipportingtire. arranged within the inner ciiciiinference of the elastic tii'e comprising 'in the forni of rods or erablv olI iinil'orin diameter ani'l are spaced apart latcrallvv so the) inav yield independl Specification of Letters Patent.

'These'rings E it will be understood are resili'ent and .may be of any suitable eross-sec tional forni, as will be understood from the drawing in which in Figs; 2 and'3 the rings E are'shown circular in cross-section and 1n Figs. 6 tof12 inclusive, different These rings E to extend and support te elastic tire (viel inde eiidently' as pressu e maybe'applied to tfie elastic tire, they being fitted tightly thereto 'and having a tendency to- 'bed into the rubber ofthe elastictire and thus aid l in keeping thesaid elastic tire from lateral displacement. -We have shown sixrings but manifestly the number would depend more or less upon the Width of the elastic tire. I-n practice after joining l the ends of the rods to form the rings E, we l lind it desirable to roll the i tliein to produce a uniform temper. i Within the supporting tire-we. arrange 'at intervals supportingfplatesF which areprovided on their outer sides with lugs F site the cavities C and extending -thereinto and within the links as best shown in Figs. 2 and 13 of the drawing. ,These supporting plates .F bear within the inner circumference of the supporting tire and are lrovided in [their outer faces with grooves 1 extending l in the direction o wheel and receivi l porting l plates at their opposite edges with outwardly projecting llanges F3' which lap yalong the l outer sides of the-elastic. tires'A and aid in l preventing lateral displacement of said tires l as best sliown in Figs. l ln practice we siipport the plates F"from'a l riiu (l by iueans of elastic blocks Il seated at their outer ends in 2 sides of tlie plates l" l in sockets G npoii t l (i as will be anders l the drawing.- h i lt will be noticed` that .thet plates l" are provided midway be Il' sides willi a lougitii iig tlie'rings E of the su and at their inner ends he outer side of the riin tween their i ,keep the rings or hoopxs'in pos Y forms are while operating rings after joining :3 and 3 of the drawing.

It will also be .noticed that the sectionalring construction of the supporting tirefoperates in connec-A ties at intervals,.reinforcing rings of rod or vstout wire extending along the opposite sides ofthe elastic tire, studs connected' withthe said side rings at points opposite the cavities in. the elastic vtire and extending thence intov said cavities, connecting means between the inner ends ot said studs, plates arranged within the inner circumference of the elastic tire and provided with lugs projecting into the cavities therein and engaging with the conncetiinT means `between the' opposite studs, anni a supporting tire consisting oi independent rings exten( ing between the elas- 'independent ri'ngs of the supporting tire,`-
